TV reception worsens after
connecting the unit.
This can occur because the signals are being divided between the unit and
other equipment. It can be solved by using a signal booster, available from
electronics retailers.

After DVB Auto-Setup only some or
no DVB channels are found.
Check to ensure your area is covered by DVB transmissions.
Check that the aerial and antenna cable are designed for DVB.
Use the supplied RF coaxial cable shown in STEP 2, Basic Connection.
If you live within 5–10 km of DVB transmission towers, a combined VHF/
UHF aerial should be adequate. Outside this area, separate VHF and UHF
aerials provide superior reception performance.

this unit and antenna wall socket to minimise impulse noise pickup. If
problem persists consult your local TV aerial installer.
When “No Signal” message is displayed, check aerial connection.
Adjust the aerial reception with “DVB Manual Tuning”.
